Re: Is a throtle bottle upgrade worth it 2005 CTSV

TBs have mixed reviews.. Some say you need a tune to take advantage of the extra air and make it run reliably.which i agree with.. and then even if you do get it running right its only a 5 BHP mod.. soo basically you changed your acc drive setup.. IMO..it would make a bigger difference down the road with a nice heads and cam setup. since the LS6 intake flows well.. I would just port the stocker and get a tune when i did another real mod like uncatted headers
